Thirdly by pcr (polymerase chain reaction) which ...Read more

If someone has HIV and shows symptoms of HIV will they test positive for it if it's during the window period?

If someone has HIV and shows symptoms of HIV will they test positive for it if it's during the window period?

Contradiction in: terms. Window period is a few weeks after acquiring infection. If there are symptoms of HIV, it is no longer in the window period. ...Read more

What is the true Window period for HIV? I have had a test 5 months after exposer to a women with unknown risk it was negative and it still worries me.

6 months is: probably a good time to stop testing post exposure. I would recheck again in 1-2 months and if that is negative, I wouldn't worry anymore. ...Read more

What is the window period of HIV test?

Time to turn positiv: After you get infected w/hiv (not every exposure leads to infection), there is a period of time where your tests will remain negative, depending upon you & your test. Therefore, you can also get HIV from someone who tested negative! assuming they tested during their window period.

If I'm showing signs and symptoms of hiv, even if its before the window period is up, will I be able to test positive?

Depends: It is very unlikely that your symptoms are due to HIV, if you are in the window period. By definition, antibody tests are negative in the window period. If you get a HIV nucleic acid test, that is the earliest test to turn positive in a person with HIV. But a negative result on a test done too soon does not rule out infection.

Window periods hiv test. I had 4 test hiv combo after 94 days negative.But my country state window period 6 month. Malaysia. ?

Window periods hiv test. I had 4 test hiv combo after 94 days  negative.But my country state window period 6 month. Malaysia. ?

4 weeks. Believe it.: Only a few companies make most of the HIV tests used worldwide. The window period for the combo test (also called duo or 4th generation test) is the same everywhere, 4 weeks. That a particular health department or agency takes a conservative stance and promotes longer periods is a decision based on legalities, politics, and social context. I can't say why some agency in Malaysia says 6 months. ...Read more

If I test negative for HIV three months after my last encounter, should I be fine? 3 months is the appropriate window period right?

If I test negative for HIV three months after my last encounter, should I be fine? 3 months is the appropriate window period right?

That's up to you: Consider yourself healthy if it's one of the new-style tests that's essentially always positive by 3 months (actually quite a bit less). But you will be FINE when you become a mature lover, always loving safely out of respect for your own body and for the other person's. Don't put yourself or anyone else in situation like this again. Think ahead of the love with that one special lifetime person. ...Read more

Is it possible to have a false negative rapid HIV test well after window period (9 months after last possible exposure)? If so , why?

Is it possible to have a false negative rapid HIV test well after window period (9 months after last possible exposure)? If so , why?

Unlikely: When sufficient time has elapsed after one's last potential exposure, HIV tests are usually reliably positive if one is in fact infected. One has to be aware that the usual test looks for hiv-1, but there is also an hiv-2 which is far less common but could be in you and the standard test would not recognize it. ...Read more
